MONTGOMERY — Graffiti artists of a sort turned a highway distance marker sign into a simple arithmetic lesson with just a few pieces of white tape.

Travelers on Route 206 southbound, just north of the Montgomery Center shopping plaza have been able to brush up on their math while heading toward Princeton, Lawrenceville and Trenton in recent days.

An arguably clever vandal used white tape to turn the three town distances into a basic arithmetic problem, adding up the the 4 miles to Princeton and the 9 miles to Lawrenceville to equal the 13 miles to Trenton.

"We are contacting the NJDOT to remove the tape," Lt. James Curry of Montgomery Police said. "I can't recall it happening in the past."
